RepRap Specifications 0.5 mm resolution in
the X&Y directions
0.1 mm resolution in the Z direction
Material: Biodegradable plastic

Why RepRap? 3D printing
Cost: $800 vs. >$15,000
Can print itself
Open source project

Project goals1. To build a RepRap
2. To add 2D solid wire embedding capability to RepRap
3. To document the new design on the RepRap wiki according to open-source standards

RepRap Plastic Extruder Melts plastic filament and
pushes it through a small nozzle
Plastic is squeezed between a motor shaft and a bearing

RepRap Mechanical Design Each axis controlled by a stepper motor
Extruder moves in X-Y plane
The Z platform moves down after each layer

Wire Embedding Module Tasks:
Feed wire
Bond wire to part
Cut wire
![Page 11: Wire-embedding 3D printer](https://reader035.fdocuments.us/reader035/viewer/2022062520/56816301550346895dd379ad/html5/thumbnails/11.jpg)
Feed Wire Same method
as plastic extruder
Pinch wire against motor shaft
![Page 12: Wire-embedding 3D printer](https://reader035.fdocuments.us/reader035/viewer/2022062520/56816301550346895dd379ad/html5/thumbnails/12.jpg)
Bond wire to part
Create a “hot zone” on the plastic surface
